Valent ReTain CA Almonds

This App predicts almond bloom progression once bloom has started (first open blooms in the interior of the orchard). This new tool utilizes machine learning technology, orchard-specific data, and localized weather data. This App provides a prediction of when to apply ReTain® Plant Growth Regulator for California to correspond with 30% to 60% bloom, which research has shown is the best timing to apply ReTain in almonds to maximize the potential for fruit set.


Always read and follow all product label information as well as supplemental technical information before any application of ReTain. This App requires the creation of a user account for log-in and app function and is intended for users of ReTain in California almonds only. For account setup, please contact an authorized Valent U.S.A. LLC representative.
